I’m surprised this does not mention humans can grow back the tips of their fingers (past the white part of cuticle) https://www.npr.org/sections/health-shots/2013/06/10/1903854... Supposed to be only kids but I’ve chopped off a few mm by accident it came back as an adult or I can’t tell the difference.

The exact same thing happened to me. I chopped off a good half a cm with an axe when splitting firewood about 5 years ago. After no less than 6 months there wasn’t any sign of the mutilation.

Does your fingerprint look normal? When I was a kid I was goofing around with a pair of scissors and lopped off a good chunk of the pad of one finger. Thirty years later my fingerprint looks like a bunch of little dots at that location. The ridges never grew back properly.

2 years I ago I sliced maybe 1.5mm frommy thumb-tip; when taking off the bandage, I could clearly see the "straight cut" and that some material was missing.

Until today, it recovered completely

Liver as well, but I have no idea if that's the same underlying phenomenon.
